I was at this one stable, and for the first 2 summers I did very well and had that feeling of "accomplishment" like SP described. When I restarted lessons last spring (for many reasons I couldn't ride all year, but every year I would increase my number of lessons and was going to start riding regularly (finally) during the year), my trainer had no more interest in me. She would wouldn't concentrate much on me, when I was the one who needed the most help. I didn't want her to only teach me and ignore the others, but I wanted the same care and instructions she was giving to everyone else. I think it's because she thought I wasn't serious about riding, that I only planned on taking lessons in the summer for the rest of my little life.
Long story short, I couldn't stand it any longer. Talking to her about my plans and what I wanted was impossible. NO matter how bad I tried I couldn't get our relationship to grow. We really didn't click.
I was miserable, and started to dislike riding. Always getting the really old mare no one rode anymore didn't help either. She was easy to ride... when you could get her to move. She was really old and all she wanted was to sleep and eat in the pastures all day. She didn't want to be ridden and did everything in her power to trick her way out of the work. She was one clever pony!
Anyhow I browsed, found a barn that was 3 times closer and found there the trainer I have today. She is very knowledgeable, and is also a bit of a "safe fanatic" which me and my parents like. I know I will never seriously get hurt while she is there, because she will make me stop immediately if she see's I am riding in a position that can possibly be dangerous.
She is also very open, sociable and I can easily open up to her and tell her things.
